| 20090207067 | Radar Imaging of Buildings Using Model-Based Focusing and Data-Based Focusing - According to one embodiment, an image generating device includes an image former coupled to a radar that transmits and receives electro-magnetic radiation at multiple frequencies. The image former generates an image using information received from the radar, adjusts the image according to a material characteristic of the object, and combines the image with other images received at differing frequencies to form a resulting image. | 08-20-2009 |

| 20080246875 | SYSTEM AND METHOD FOR FREQUENCY TRANSLATION USING AN IMAGE REJECT MIXER - Frequency translation, such as frequency up conversion of a video baseband or intermediate frequency to a desired frequency division broadcast channel, is provided utilizing a single sideband or image reject mixer and filtering having relaxed selectivity requirements. According to a preferred embodiment, a first single sideband mixer accepts an input signal at an intermediate frequency and up converts this signal to a high intermediate frequency. The image rejection provided by the single sideband mixer in combination with simple filtering provide sufficient signal quality to achieve desired levels of desired signal isolation, such as on the order of 40 dB. Preferably, a second single sideband mixer accepts the high intermediate frequency signal and down converts this signal to a desired transmission or broadcast frequency. The image rejection provided by the single sideband mixers in combination with simple filtering provide sufficient desired signal isolation, such as on the order of 40 dB, thereby relax the linearity requirements of amplifiers utilized in the frequency translation system. A preferred embodiment of the present invention disposes all or substantially all the frequency translation circuit elements on a single substrate. | 10-09-2008 |
| 20090066847 | BROADBAND INTEGRATED TUNER - A broadband integrated receiver for receiving input signals and outputting composite video and audio signals is disclosed. The receiver employs an up-conversion mixer and a down-conversion mixer in series to produce an intermediate signal. An intermediate filter between the mixers performs coarse channel selection. The down-conversion mixer may be an image rejection mixer to provide additional filtering. | 03-12-2009 |
| 20100265412 | Broadband Integrated Tuner - A broadband integrated receiver for receiving input signals and outputting composite video and audio signals is disclosed. The receiver employs an up-conversion mixer and a down-conversion mixer in series to produce an intermediate signal. An intermediate filter between the mixers performs coarse channel selection. The down-conversion mixer may be an image rejection mixer to provide additional filtering. | 10-21-2010 |

| 20090219451 | Broadband Integrated Television Tuner - A broadband integrated television receiver for receiving a standard antenna or cable input and outputting an analog composite video signal and composite audio signal is disclosed. The receiver employs an up-conversion mixer and a down-conversion mixer in series to produce an IF signal. An IF filter between the mixers performs coarse channel selection. The down-conversion mixer may be an image rejection mixer to provide additional filtering. The received RF television signals are converted to a standard 45.75 MHz IF signal for processing on-chip by additional circuitry. | 09-03-2009 |
